Beta Chain Wear Indicator - 3935

Overview

Beta Tools chain wear indicator is a compact bicycle tool designed for fast, reliable checking of chain elongation during routine servicing and maintenance. A worn chain can lead to poor shifting, increased sprocket wear and a greater risk of sudden breakage, so regular inspection is an important part of drivetrain care. This chain wear indicator uses a simple pass/does not pass system to show whether the chain remains within an acceptable wear range or has stretched enough to require replacement. Its straightforward format helps mechanics, cycle workshops and service technicians make quick assessments without unnecessary guesswork. With a compact 120 mm length and lightweight design, it is easy to keep in a toolbox, workshop bench setup or mobile service kit for regular bicycle maintenance.
